Hi all:

Please remember that anything intended to kill insects that chew on wood
may also present a hazard to bees and your products.  If you have been
using treated wood, and haven't had a problem, that's fortunate.  What the
effects, if any, be would vary with the chemical, age of the wood,
weathering, etc.  What I can say for certain is that most of these
chemicals will off-gas to some degree, and those fumes we can detect in the
air inside the hive.

Finally, there is a new book on the market that deals with bees and
chemicals, ranging from pesticides to radioactive materials.  Title:  Honey
Bees: Estimating the Environmental Impact of Chemicals, Taylor and Francis
books.

Although I co-authored 2 chapters, I don't get any royalties - so I offer
this for your information.  I haven't seen it yet, but one chapter deals
with the effects of imidacloprid on bee memory.  Overall, the book should
contain information that has not been previously available - the works are
either very recent or so voluminous that no journal wanted to publish them.
 Total book is over 300 pages.

Cheers
